The following description of the preferred embodiment is provided to understand the features and the structures of the present disclosure.

Please refer to FIG. 1 to FIG. 3, which are a structural view and a block view showing a preferred embodiment according to the present disclosure; and a view showing a loading tray. As shown in the figures, the present disclosure is an automatic genechip array diagnosing apparatus, comprising a loading tray 1, an active mixing device 2, a temperature controlling device 3, a reagent storing device 4, a fluid manipulation device 5, a magnetic controlling device 6, an image acquiring device 7 and an operating device 8.

On a surface of the loading tray 1, the loading tray 1 has a sample pretreatment area 11, a sample purification area 12, a transcription and probe labeling area 13 and a genechip reaction and imaging area 14, where the loading tray 1 is used as an operation platform for loading a sample and a genechip array on processing a diagnosis. The genechip reaction and imaging area 14 is set with a genechip array 141; and each genechip in the genechip array 141 has a plurality of probes. A chemical enzyme colorimetric development method is processed after a reaction between the sample and the probes in the genechip array 141.

The active mixing device 2 is connected with the loading tray 1, which shakes the loading tray 1 on processing the diagnosis. The active mixing device 2 is a servo motor.

The temperature controlling device 3 is connected with the loading tray 1, which controls temperature of the loading tray 1 on processing the diagnosis.

The reagent storing device 4 comprises a plurality of reagent vessels 41 and a magnetic beads storing area 42, which provides a reagent for the sample on processing the diagnosis.

The fluid manipulation device 5 is set between the loading tray 1 and the reagent storing device 4, which provides the reagent to the loading tray 1, transfers the sample between areas of the loading tray 1 and discharges a waste liquid generated after the reaction of the sample. The fluid manipulation device 5 is a vacuum suction device.

The magnetic controlling device 6 is connected with the loading tray 1, which purifies the sample with coordination of a plurality of magnetic beads in the magnetic beads storing area 42.

The image acquiring device 7 is corresponding to the genechip reaction and imaging area 14, which takes photos of the sample and the genechip array after the reaction and a development process. The image acquiring device 7 is a photosensitive device.

The operating device 8 is connected with the loading tray 1, the active mixing device 2, the temperature controlling device 3, the reagent storing device 4, the fluid manipulation device 5, the magnetic controlling device 6 and the image acquiring device 7 to control operation, analyze photo and show data. The operating device 8 comprises a processing unit 81; an input unit 82 connected with the processing unit 81; and an output unit connected with the processing unit 81, where the processing unit 81 is a programmable logical array; where the input unit 82 comprises a plurality of pressing bottoms; and where the output unit 83 is a display.

Thus, a novel automatic genechip array diagnosing apparatus is obtained.

On using the present disclosure, a method is processed with the following steps:

(a) A sample (e.g. blood) is transferred to the sample pretreatment area 11 of the loading tray 1 injected with a lysis processing solution. The sample pretreatment area 11 is then heated to a temperature of 35˜80° C. by the temperature controlling device; and, the magnetic beads and a reagent for separation and purification in the magnetic beads storing area 42 of the reagent storing device are transferred to the sample pretreatment area 11 by the fluid manipulation device 5. Then, the active mixing device 2 shakes the loading tray 1 at a speed of 100˜200 rpm to mix the sample, the magnetic beads and the reagent for effectively jointing the magnetic beads with the sample.

(b) The sample jointed with the magnetic beads in the sample pretreatment area 11 is transferred to the sample purification area 12 by the fluid manipulation device 5. Then the sample is purified by attracting the magnetic beads with the magnetic controlling device 6. A supernatant without the magnetic beads in the sample purification area 12 are then removed by the fluid manipulation device 5.

(c) A reaction solution obtained from the reagent vessels 41 by the fluid manipulation device 5 is added into the sample purification area 12; and, the magnetic controlling device 6 is shut down to make the magnetic beads float. The active mixing device 2 then shakes the loading tray 1 at a speed of 100˜200 rpm to fully mix the magnetic beads with the reaction solution. Thus, after the sample and the magnetic beads are separated, molecules are released.

(d) A solution containing the molecules in the sample purification area 12 is transferred to the transcription and probe labeling area 13 by the fluid manipulation device 5. The reaction solution in the reagent vessels 41 is sucked into the transcription and probe labeling area 13 by the fluid manipulation device 5. The active mixing device 2 shakes the loading tray 1 at a speed of 100˜200 rpm; and, the transcription and probe labeling area 13 is heated to a temperature of 35˜80° C. by the temperature controlling device 3. Thus, a reaction of transcription and labeling to the sample is accomplished.

(e) After the transcription and labeling in the transcription and probe labeling area 13 is accomplished, the molecules of the sample are transferred to the genechip reaction and imaging area 14 by the fluid manipulation device 5 for reaction. A plurality of reaction solutions in the reagent vessels 41 is sucked by the fluid manipulation device 4 to be placed into the genechip reaction and imaging area 14. Then, the active mixing device 2 shakes the loading tray 1 at a speed of 100˜200 rpm; and, the genechip reaction and imaging area 14 is heated to a temperature of 35˜80° C. by the temperature controlling device 3. Thus, a specific bonding is done by probes in the genechip array 141 for development with a reagent.

(f) A developed photo is obtained from the genechip reaction and imaging area 14 through the image acquiring device 7 after the bonding reaction of the molecules and the probes in the genechip array 141. The photo is then discriminated, transferred or showed through the input unit 81 and the output unit 82 of the operating device 8 with coordination of the processing unit 83. The photo taken by the image acquiring device 7 is thus analyzed to finish diagnosing the specific molecules in the sample.

Thus, the present disclosure operates an automatic diagnosis through the above steps with coordination of devices disclosed in the present disclosure for reducing manual error, accelerating reaction speed, and shortening diagnosis time.

To sum up, the present disclosure is an automatic genechip array diagnosing apparatus, where a sample is diagnosed with automatic devices for a fast diagnosis having high accuracy.
